Hi,
try installing this app

"The Windows 10 Mobile Upgrade Advisor app helps you find out if your Windows Phone 8.1 phone is eligible to install the upgrade to Windows 10 Mobile. "

638 seems to be supported

@HotCakeX Desculpa se eu estiver errado, mas a Microsoft não tinha "fechado" a loja para o Windows 8.1?

Windows mobile is deprecated, it's not longer an active product.

there is only one store, Microsoft store, that is available for mobile, Xbox, surface, PC, HoloLens etc.

and there are some apps that still are for Windows mobile in the store.
